Prism – Composite Application Guidance for WPF and Silverlight – October 2009


This minor update of the Composite Application Guidance for WPF and Silverlight allows you to use the Composite Application Library with Silverlight 3. The following changes were implemented in this release:

  • All Visual Studio projects (Composite Application Library, reference implementation, and Quickstarts) were migrated to use Silverlight 3. If you do not want to upgrade to Silverlight 3, see Opening Projects with Silverlight 2.
  • TabRegionControlAdapter was modified to support binding in the TabItem‘s control header in Silverlight 3. This feature was present for Silverlight 2 but stopped working in Silverlight 3 due to a breaking change. It now supports both versions of Silverlight.
  • Implemented the WeakEvent Pattern for the DelegateCommand‘s and CompositeComand‘s CanExecuteChanged event to fix a possible memory leak in the applications using the Composite Application Library commands. For more information, see Composite Application Library Command Memory Issues and Solution.
  • CreateXap.bat file was modified to search for Silverlight 3 assemblies if the Silverlight 2 reference assemblies cannot be found. This is to support the infrastructure required to run the Composite Application Library unit tests. Applications already using the library will not be affected
